I'm going to catch shit for this I'm sure, but I haven't been a big fan of Metallica's live performances since the Black album. Last time I saw them was in 97 at MSG and wasn't impressed (nor have I been watching them on TV live since). Now their live stuff during and before 91 was unreal. I saw Maiden in 2000 at MSG and they were equally amazing, and I'm not a huge Maiden fan. I try and see as many acts live to support the bands as I can, but like me, they're not getting any younger. My favorite, AC/DC, are probably done. Their lead singer is 65 years old.
